ANSI/AAMI ES60601-1 Medical Electrical Equipment - Part 1: General Requirements for Basic Safety and Essential Performance

The standard “ANSI/AAMI ES60601-1 Medical electrical equipment - Part 1: General requirements for basic safety and essential performance”, published jointly by the American National Standards Institute (ANSI) and the Association for the Advancement of Medical Instrumentation (AAMI), describes the safety and essential performance requirements for all medical electrical equipment.

This standard contains requirements for the basic safety and essential performance of all medical electrical equipment used by or under the supervision of qualified personnel in the general medical and patient environment. It also contains specific requirements for reliable operation to ensure safety. This standard is also applicable to equipment used in the compensation or alleviation of disease, injury or disability. However, these requirements do not cover the hazards inherent in the intended physiological function of medical equipment or medical systems.

Essentially, this standard is based on the “IEC 60601-1 Medical electrical equipment - Part 1: General requirements for essential safety and essential performance” standard published by the International Electrotechnical Commission (IEC). This standard addresses the essential safety and essential performance of medical electrical devices and medical electrical systems. The IEC 60601 standards are a widely accepted set of standards aimed at ensuring the essential safety and essential performance of medical electrical equipment.

For the purposes of this standard, the following terms and definitions apply:

• Abnormal use is the intended action or intended omission of action by the user or operator of the equipment that results from behavior beyond the manufacturer's reasonable means of risk control.
• Efficiency is the accuracy and completeness with which operators achieve specified objectives.
• Efficiency is the resources expended in relation to the accuracy and completeness with which operators meet targets.
• The operator-equipment interface is the means by which the operator and equipment communicate.
• The operator profile is a summary of the mental, physical, and demographic characteristics of the intended operator population and any special characteristics that may have an impact on design decisions, such as occupational skills and job requirements.
• A priority operating function is one that involves operator interaction that is relevant to the safety of the equipment in frequent or normal use.
• Reasonably foreseeable misuse is the use of the business in a way that was not intended by the manufacturer but could result from easily foreseeable human behavior.
• Operation error is an action or omission of action by the operator resulting in an equipment response different from that intended by the manufacturer or expected by the operator.
• A use case is a sequence of events and tasks used to determine and test the usability of equipment.
• It is the feature that ensures usability, effectiveness, efficiency and operator learnability and satisfaction.
• Validation is the verification through provision of objective evidence that the requirements for a particular intended use or application are met.

Equipment outside the scope of the ANSI/AAMI ES60601-1 standard includes:

• In vitro diagnostic equipment that does not fall within the definition of medical equipment within the scope of this standard
• Implantable parts of active implantable medical devices within the scope of the ISO 14708 series
• Medical gas pipeline systems covered by the ISO 7396-1 standard

Electrical safety testing is used to ensure that medical equipment is electrically safe during use in a healthcare environment by testing for faults or damage. Medical device safety testing is more stringent compared to general electrical devices. Patients are exposed to significant electrical hazards because they are directly connected to electrical devices.

Medical electrical safety analyzers are developed with measurement circuits to simulate the typical impedance and electrical properties of the human body. These circuits are called body models and are specified in electrical safety standards, including the IEC 60601-1 standard.
